Mazapertine (RWJ-37796) is an antipsychotic agent that was developed by Johnson & Johnson but never marketed. It exerts its pharmacological effect through affinity for dopamine D2, serotonin 5-HT1A, and α1-adrenergic receptors.[1]
Mazapertine is safe and well tolerated when administered orally.[2]
Analogs of mazapertine with conformational restriction have been prepared and have greater affinity for the 5-HT1A receptor.[3]
Synthesisedit
The laboratory synthesis of mazapertine has been reported.[4][5][6] It begins with alkylation of 2-nitrophenol (1) with isopropyl bromide to give 2-isopropoxynitrobenzene (2). Catalytic hydrogenation of nitro group gives 2-isopropoxyaniline (3). Intermolecular ring formation of this aniline with bis(2-chloroethyl)amine yields 1-(2-isopropoxyphenyl)piperazine (4). Separately, amide formation of 3-(chloromethyl)benzoyl chloride (5) with piperidine gives 1-3-(chloromethyl)benzoylpiperidine (6). The last step is the convergent synthesis between the above two arms of the synthesis to afford the alkylation product mazapertine (7).
